Generate correctly formatted random email addresses with support for custom domains and prefix rules. Ideal for testing registrations and privacy protection scenarios.
Click generate to create a batch of emails
When you need a large number of test emails or want to protect your real email address, creating them manually is both time-consuming and prone to duplication. This tool uses algorithms to bulk generate RFC-compliant random email addresses. Its core function is to generate a string combining an alphanumeric local part (username) with a valid domain name. Each generation outputs a plain text list of emails that can be directly used for test data population or temporary registrations.
Q: Can the generated emails actually send and receive messages?
No. The generated emails are simply correctly formatted strings. They are not real email accounts and are strictly for testing and placeholder purposes.
Q: What are the format requirements when entering a domain?
It must follow the standard domain format (e.g., example.com). Do not include "http://" or "www" prefixes, as this may result in invalid generation.
The generated emails cannot be used for real communication. Ensure the format is correct when using a custom domain. We recommend generating no more than 100 emails at a time to avoid performance issues. Do not use this tool in scenarios involving sensitive information.
For constructing test data, we recommend using your company's own domain (e.g., test.com) to generate emails, as this better aligns with real business scenarios. Typical example: Entering the domain "example.com" with a length of 6-10 characters in mixed mode might generate a result like "a1b2c3@example.com". Note that while the generated emails are correctly formatted, there is no risk of email leakage since no actual email service exists for them.
